Letters .Patent No. 90,379, dated May 2 5, 1869.

IMPROVEMENT IN LEVELLING- HYDRAULIC G-AS-MINS.

*dem- The Schedule referred to in these Letters Patent and making part of the same.

To all whom, it may concern:

.Be it 'known that I, PETER MUNZINGER, ofthe city and county of Philadelphia, and State of Pennsylvania, have invented a new and useful Adjustment for Hydraulic Gas-Mains, by using adjusting or levellingscrews; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying sheet of dra-wings, and to the letters of reference marked thereon, making part of this specification, in which- Figure l is a longitudinal section, showing my method of adjusting or levelling the hydraulic main;

Figure 2 is a transverse section of the same; and

Figure 3 is a transverse section, showing the lnethod .now used of carrying and levelling the hydraulic main, -as distinguished from my improvement.

Similar letters refer to similar parts in the several views.

In the manufactureof gas, it is conveyed, by pipes, from the retorts where it is distilled, to the hydraulic main, A, entering through the dip-pipes B.

The hydraulic main is a large metal pipe, usually of cast-iron, which should be placed in a perfectly horizontal position, and be supplied with water to sui,

ciently immerse the ends ofthe dip-pipes, so that the gas can only enter the main by displacing the water, which otherwise would rise in the pipe to the same level on its inside as on its outside, and, when once in the hydraulic main, the gas cannot possibly return through the dip-pipe. Another pipe conducts the gas away to the condenser. Y

As shown in iig. 3, the hydraulic main, A, is carried by a stand, B, on the foundation O.

It will be observed that no provision has been made for adjusting or levelling the main, made necessary by the settling of the foundation, or from its surface or top not being finished perfectly true. It is generally accomplished by Wedging under the base of the stand carrying that end of the main below the horizontal line. This is a long and tedious operation, which must be carefully and skilfully carried. out; otherwise the water in the main will not cover the ends of all the dip-pipes, and the gas be permitted to escape through them.

My method of levelling the hydraulic main, A, is as follows: 4

D D are hollow stands, or columns, on the foundation E.

F are screws, which depend from the circular saddles, or carriers G, which embrace and carry the main. Theirends take into the corresponding openings formed in the stands.

A nut, H, which is carried on the tops of the stands, is iitted to each screw.

It will be seen that the screwsare stationary, by rea-son of their connection with the saddles G, and that the turning of the nuts on the said screws causes them to raise or lower, according to the direction, which elevates or depresses either end of the main, whereby it is levelled and adjusted with the finestnicety.

I w'ish it distinct-ly understood that I do not confine myself to iixed, or stationary screws and movable nuts, knowing it to be in the province of any skilled mechanic to give a rotary motion to the screws in fixed nuts, or, in lieu of fixed nuts, in corresponding screws formed in the cylindrical openings of the stands, or columns.

What I claim as my invention, and desire to secure by Letters Patent, is f y The use 'and application of levelling-screws, either fixed or movable, substantially for the purpose shown.

In testimony whereof', I hereunto sign my name in presence of two subscribing.,r witnesses.

PETER MUNZINGER.
